DEVICE FOR MIXING AND APPLYING INSECTICIDE.

SPECIFICATION forming part of Letters Patent No. 758,817, dated May 3,1904.

Application filed May 4, 1903. Serial No. 155,663. (No model.)

To all whom it may concern:

Be it known that we, IVILLIAM HENERY BROWN and JOSEPH lVINsmr, citizensof the United States of America, and residents of the city of Seattle,in the county of King and State of \Vashington, have invented certainnew and useful Improvements in Devices for Mixing and ApplyingInsecticide, of which the following is a specification.

Our invention relates to improvements in devices for mixing and applyinginsecticide, and has special reference to a device of this class whichis adapted to retain soluble matter in active communication with a flowof solvent fluid.

Among numerous objects attained by this invention and readily understoodfrom the following specification and accompanying drawings, included asa part thereof, is the production of a simplified and inexpensive devicefor use in connection with spraying apparatus to retain solubleingredients in active communication with a fluid-flow and embodyingessential features of adaptability, utility, and general efficiency,which insures thorough mixing and dissolution of the ingredients and amore scientific compounding of the admixture and avoids clogging of thedevice.

The above-mentioned and other desirable objects are attained by theconstructions, combinations, and arrangements of parts as disclosed onthe drawings, set forth in this specification, and succinctly pointedout in the appended claims.

IVith reference to the drawings filed herewith and bearing likereference characters for corresponding parts throughout, Figure 1 is aside view of the device with the casing thereof shown in longitudinalsection, taken on line 1 l of Fig. 2 and viewed as the arrows indicate,and shows the partition therein with a portion broken away. Fig. 2 isaview of the casing shown in transverse section, taken on line 2 2 ofFig. 1, looking as the arrows indicate and shown with the conical screenremoved; and Fig. 3 is a perspective view, on small scale, showing thedevice in use.

This invention includes a receptacle 9, which preferably consists of acasing 10, the main portion of which is formed tubular and preferablycylindrical and is composed of suitable sheet metal, as brass, copper,or like metal, which will not be affected by the chemicals placed in thereceptacle. This casing is provided at one end with a head 12, which ismade of sheet metal and formed with the inner surface conical shaped andis fixedly connected with the main portion of the casing and is providedwith a suitable aperture 7 at the apex, which acts as the port ofingress for the fluid, and a suitable coupling part, as 14, is securedto the head at the apex for the connection of a suitable hose or thelike with the receptacle. At the opposite end of the casing is aremovable head 14, which is composed of plate metal and formed with theinner surface conical shaped, and this head is provided with a suitableaperture 8 in the apex, which is the port of egress for the admixture,and an outwardly-extending annular flange 16 about this aperture havingscrew-threads on the periphery, by means of which a suitable nozzle orthe like can be conveniently connected with the receptacle to direct thedischarging admixture in the form of spray. This head 14: is preferablyformed with an annular shoulder 20 and an annular flange 17 of lessdiameter than the shoulder at the base end, and this flange is providedwith screw-threads on the periphery which are adapted to engagecorresponding screw-threads formed in the bore of bushing 18, secured inthe end of the cylindrical portion of the casing, and therebyconveniently provide for the detachable connection of the said head withthe casing, so that the receptacle can be separated for the placementtherein of the desired ingredients, and suitable lugs, as 19, arearranged on the outer surface of the head to afford a better grasp forthe hand to rotate the head, and a gasket is placed between saidshoulder 26 and the end of the casing to effect a fluid-tight joint.

Upon the main body of the casing is secured a longitudinallydisposedtapering handlesocket 20, composed of a section of sheetmetal ofconsiderable length which is bent lengthwise to semicircular form, and aportion of this section is bent outwardly along each side edge toconveniently provide flanges by means of which the socket is secured tothe casing by solder or the like. This socket is adapted to receive oneend of a long handle, as 31, Fig. 3, by means of which the device can bemanipulated and brought in close proximity to the branches of the treesit may be desired to spray without requiring the operator to mountladders or the like, and a thorough spraying can be effected while theoperator stands at such distance that the drippings will not fall uponhis person.

Within the receptacle is a longitudinallydisposed removable partition21, which divides the chamber into compartments. This partition iscomposed of plate metal of suitable width to fit snugly but slidably inthe casing and is formed with one end, 22, tapered to fit within thefixed head of the casing with the outer extremity thereof in closeproximity to the port of ingress at the apex of the head, so that thefluid-flow will be equally divided as it passes into the receptacle, andin the opposite end portion of this partition a substantially V-shapednotch, as 23, is formed to receive a conical screen 24:, which is placedin the discharge end of the receptacle.' Suitable in wardly-proj ectingguide-lugs 25 are secured on the inner surface of the wall of the casing10 at diametrically opposite points to guide the partition to place, andthe bushing 18 is provided with suitable slots at diametrically oppositepoints to receive the edges of the partition as it is placed in andremoved from the receptacle.

In the removable head 14 of the casing is seated a transversely-disposedperforate diaphragm 26, which preferably comprises a circular section ofperforate sheet metal, and in front of this diaphragm is placed aconicalshaped screen 24:, preferably formed of asection of pliable wirebent to conical spiral form and disposed with the base end seated insaid head adjacent the diaphragm,so that the screen will fit within thenotch in the partition and be embraced thereby. This screen is adaptedto hold the greater mass or larger particles of the ingredients employedfrom passing to the diaphragm, and thereby prevent clogging thereof,while the smaller particles or limited portions of the ingredients arecarried forward to the diaphragm and retained thereby until fullydissolved, and the partition 21 serves to divide the chamber of thereceptacle into compartments, each of which are in communication withboth ports, and in these compartments ingredients of different kinds canbe placed and are held apart by the partition, while the conical screenallows limited portions of the separated ingredients to pass forward andcommingle at the diaphragm. Thus it will be seen that the compounding ofthe insecticide will be thoroughly and scientifically accomplished andthe chances of clogging the receptacle reduced to a minimum.

By forming the screen 24: of pliable wire it can be readily extended orcontracted to vary the pitch of the convolutions in conformity with thenature" of the ingredients, so that the screen will act to properlyretain the same, and by making the screen conical in form acomparatively extensive area of screening-surface is presented as abearing-surface for the ingredients, which are thereby more fullyexposed to the action of the dissolvent, while the partition in thereceptacle renders it possible to use such ingredients as would combineand clog the receptacle if placed together therein en masse, and theconical form of the interior surfaces of the walls of the heads of thecasing serves to insure a more equal distribution of the dissolvent tothe compartments and free passage of the admixture to the port ofegress.

When desired to use the receptacle for spraying trees or shrubbery withinsecticide, the removable head is unscrewed and the desired ingredientsor compounds are placed in the compartmentsas, for example, whale-oilsoap is placed in one compartment and paris green in the othercompartment. The head is then replaced and an ordinary spray-nozzleconnected therewith. The receptacle is then coupled to an ordinarygarden-hose, as 27, Fig. 3, which is connected with a source offluid-supply delivered under pressure. An elongated handle is thenseated in the socket on the casing and the device stands ready for use.

This device is simple and inexpensive of construction, has few partslikely to get out of order, and acts in a most scientific manner incompounding insecticide or the like.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent of the United States of America,

1. The combination of a receptacle of the nature indicated comprising acasing provided with a port of ingress and a port of egress, a perforatediaphragm arranged in said casing intermediate said ports, and a screenadjacent said diaphragm comprising a conical spiral.
